The purpose of secondary containment is to protect the environment from accidental leaks and spills from bulk storage tanks, which if left unchecked, could contaminate surface water or ground water, and effect health and human safety.
The federal government recognizes the importance of secondary containment and mandates by law the use of a secondary containment system consisting of one of the following: 1. A liner (external to the tank)2. A concrete containment vault (with chemical-resistant waterstop in all joints)
3. Double wall tank systems
4. An equivalent device as approved by the EPA Regional Administrator. All of the aforementioned systems must be designed so that they can contain 100 percent of the capacity of the largest tank within its boundary. (See EPA Title 40 CFR 265.193 [new construction] and Title 40 CFR 264.193 [retrofit] for more information.) Due to aesthetics and functionality, most owner-operators choose to utilize concrete containment vaults as their preferred secondary containment system. Concrete allows for vehicular and worker traffic, has a long lifespan, and is economical. However, a concrete secondary containment structure can rarely be designed monolithically, and for that reason, Earth Shield Chemical Resistant Waterstop is installed in all concrete joints. Earth Shield Chemical Resistant Waterstop is available in a multitude of shapes and sizes for both new construction and retrofit. Please see TPV Product Catalog or Stainless Steel Catalog.
